WASHINGTON 
Sen. John Kerry, President Barack Obama’s nominee for secretary of state, collected pledges of support Thursday and testified at his confirmation hearing that U.S. foreign policy should be defined by a helping hand as well as military strength.

The Massachusetts Democrat discussed Iran, Syria, climate change and a variety of issues with members of the Foreign Relations Committee at a hearing that recalled an unusual American life — son of a diplomat, Navy lieutenant who volunteered for Vietnam, anti-war protester, five-term senator, unsuccessful nominee for president, and Obama’s unofficial envoy.

“American foreign policy is not defined by drones and deployments alone,” Kerry said in outlining his views. “We cannot allow the extraordinary good we do to save and change lives to be eclipsed entirely by the role we have had to play since Sept. 11, a role that was thrust upon us.”

Kerry spoke out strongly for dealing with climate change, providing food and energy security and humanitarian assistance. He also spoke of robust foreign aid, but he insisted that the country must get its fiscal house in order to lead in the world.

Faced with Iran’s nuclear program, Kerry said the United State will do what it must to prevent Tehran from obtaining a nuclear weapon, but he also signaled that diplomacy remains a viable option.

The senator said he was hopeful that the U.S. and other nations could make progress on the diplomatic front, but that Tehran needs to relent and agree to intrusive inspections.

“If their program is peaceful, they can prove it,” he said.

In an unexpected exchange, Kerry found himself defending Obama’s pick of Republican Chuck Hagel to be the next defense secretary against GOP criticism.

Sen. Bob Corker, the senior Republican on the panel, expressed concerns about Hagel’s support for an 80 percent reduction of U.S. nuclear weapons, a major issue for the Tennessee lawmaker and his home state.

“I know Chuck Hagel. And I think he is a strong, patriotic former senator, and he will be a strong secretary of defense,” Kerry said.

On Syria, Kerry was asked about his outreach to President Bashar Assad, now an international pariah after months of civil war and unending violence against his citizens.

Kerry said there was a moment where Syria reached out to the West but that the moment has long passed.

“History caught up to us. That never happened. And it’s now moot, because he has made a set of judgments that are inexcusable, that are reprehensible, and I think is not long for remaining as the head of state in Syria,” the senator said. “I think the time is ticking.”

Sen. John McCain, R-Ariz., a fierce critic of Obama’s policy on Syria, said the status quo is unacceptable with the United Nations estimating that 60,000 have been killed and the heavy influx of refugees in Jordan and Turkey.

After a recent visit to the refugee camps, McCain warned that Syrians frustrated with the U.S. response will be a recruitment target for extremists.

“We can do a lot more without putting American boots on the ground,” McCain said. “Otherwise, we will be judged harshly by history.”

Kerry said it was imperative to continue discussions with Russia and others in dealing with Syria but that “I don’t have optimism.” Menendez noted that Kerry, if confirmed, would be the first senator on the panel in a century to ascend to the Cabinet post. President William McKinley appointed Ohio Sen. John Sherman to the post.
